I need a productivity app developer

I need an app that will track tasks and deadlines within a graphical GUI with a fun, video game like presentation. User input will be tasks chores projects deadlines and time limits, as well as declaring tasks to be completed, output will be a simple graphical display of tasks. Prompts when time limits run out. For more details I'd say habitica is along the lines of what I need done, but much much less graphic intensive.
